You can configure the Pod placement of the Trino pods as described in Pod Placement.
The default affinities created by the operator are:
Co-locate all the Trino Pods (weight 20)
Distribute all Pods within the same role (coordinators, workers) (weight 70)
Additionally the operator will look through every
TrinoCatalog you configure and will set up the following affinities:
Hive + Iceberg connector: Co-locate the coordinators with the hive metastores (weight 50)
Hive + Iceberg connector: Co-locate the workers with the hdfs datanodes (if hdfs is used) (weight 50)
